What is the area of the composite figure?

100 cm^2

Step-by-step explanation:

rectangle = 14 x 5 = 70

triangle = (1/2)bh = (.5)(5)(12) = 30

70 + 30 = 100

answer: b.

step-by-step explanation:

it is b. cause the equations are put in the right category

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
